NUT-LOG K.

SPECIFICATION forming part of Letters Patent No. 223,909, dated January 27, 1880. Application filed October 27, 1.879.

To all whom it may concern:

Be it known that I, JAMES HENRY HAYES, of Gerro Gordo, in the county of Piatt and State of Illinois, have invented a new and Improved NutLock, of which the following is a specification.

The object of my invention is to provide a new and improved nut-lock, which shall be simple in construction, convenient, and effect ive in use.

The invention consists in a nut-lock formed of U-shaped spring, which is provided with small lugs at the-forward ends.

In the accompanying drawings, Figure 1 shows a perspective view of one part of a railjoint with fish-plates provided with my improved nut-lock. Fig. 2 represents a vertical cross-section of the same. Fig. 3 is a vertical 1 cross-section of a modification of the same. 20

sides, and provided with lugs F F at the ends.

The strip E is passed over the edges of the nuts, and is driven forward in the direction of 1 the arrow a until it is in the position shown in Fig. 1. the lugs F F glide over the nuts; but the spring of the metal will press the strip closely to the nuts, so that the lugs F F can prevent any accidental movement in the direction of The ends separate sufficiently to let 3 5 the length of the strip. The bevel of thestrip and the nuts will prevent any movement in the direction of the arrow 1).

The invention may be modified, as represented in Fig. 3. The U-shaped strip E and the nuts D are not beveled; but a Washer, G,

is interposed between the nut l) and the fishplate B, and the strip E is provided with a flange, H, on the side, resting against the fishplate B. This flange passes into the space between the nut D and the plate B, andpre o vents the strip from being moved in the direction of arrow W, in the same manner that the beveled strip prevents the beveled. nuts from moving, as described above. The ends of the strip are also provided with the lugs F F, for the purpose described above.

This nut-lock, as above described, can be used for any number of nuts exceeding two.

Having thus described my invention, what I claim as new, and desire to secure by Let- 6o ters Patent, isi In nut-locks, the U-spring E, having lugs F, and adapted to be driven on the nuts, as described.
